About Us

As Architectural Digest observed, interior designer Katie Ridder’s interiors are "a richly layered extravaganza of exotic patterns and bright hues, peppered with venerable antiques." A member of Elle Décor's A-List, she has appeared on the House Beautiful and New York magazine's "Top 100" designer lists. Clients from Switzerland to Kentucky have commissioned her to design the interiors of spaces as varied as Japanese pavilions, Palm Beach estates, Park Avenue apartments, and downtown lofts. 

Her successful wallpaper and fabric lines are represented at Holland & Sherry showrooms throughout the country, as well as in Europe. Her work has been published in Architectural Digest, Elle Décor, Veranda, Town & Country, House & Garden, House Beautiful, The New York Times and Wall Street Journal, and is the subject of the monograph Katie Ridder Rooms. She is also the author of the bestseller A House in the Country, written with her husband, architect Peter Pennoyer. Katie serves on the board of directors for The Garden Conservancy and is on the Horticulture committee at the New York Botanical Garden and Wave Hill. She is the author of Katie Ridder: Rooms and the newly released, Katie Ridder: More Rooms.

Top image: In the living room of a Manhattan apartment, the Lee Jofa fabric on the corner sectional sofa was upholstered in reverse to soften its effect against the bold persimmon walls and Studio Four’s geometrically patterned rug. Middle image (left): The de Gournay scenic wallpaper in this New Jersey dining room incorporates a portrait of the family dog, Winston. Middle image (right): In this Connecticut living room, the curtains and upholstery are a dusty pink. We contrasted this unusual color choice with a bright orange de Gournay wallpaper. All the other elements on the room, from the Seguso chandelier to the colossal Indian mirror on the architectural trim, are white. The steel coffee table, a crisp modern note, is from Gerald Bland. The embroidered leaf pattern on the leading edge of the curtains is by Penn & Fletcher. Bottom image: The bookcases in this Manhattan guest room are built into a fully curtained bed wall. The fabric of the curtains, walls, and Roman shades, in a colorway developed specifically for this room, is from Lisa Fine Textiles.
